Lens Barrel Flexible Substrate Through-Hole Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lens barrel designs face inefficiencies in making electrical connections between electronic parts inside the housing and external members due to the cumbersome process of threading a flexible substrate through holes, leading to diminished work efficiency.
Innovation Solution
The lens barrel design incorporates a flexible substrate with connection terminals positioned inside a through-hole in the cover member, allowing for easy electrical connection by supporting the substrate with first and second support bosses, which simplifies the assembly process and prevents erroneous sandwiching during attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible substrate is passed through a hole provided to a mounting component, then electrical connection between electronic part and external member is achieved, but the work becomes troublesome and work efficiency is diminished
Solution Approach 1:
The through-hole is formed in the cover member before final assembly, and the flexible substrate is positioned with its connection terminal inside the through-hole before the cover member is attached to the housing. This preliminary positioning eliminates the need for threading operations during assembly, thereby improving work efficiency while maintaining reliable electrical connection
2Ease of manufacture
If the flexible substrate is threaded through the hole, then electrical connection is established, but the process becomes complex and time-consuming
Solution Approach 1:
The connection terminal of the flexible substrate is positioned inside the through-hole before the cover member is attached to the housing. This preliminary action allows the electrical connection to be established without time-consuming threading operations during the assembly process
Solution Approach 2:
The threading operation is extracted from the assembly process entirely. Instead of threading the flexible substrate through the hole during assembly, the connection terminal is positioned inside the through-hole beforehand, eliminating the threading step and reducing assembly time
